SignHere

Freelancers and small business owners might take interest in SignHere.  This app lets users create invoices, have them sent and signed digitally, and even accept payment through Square.

Watch It Grow

Watch It Grow allows users take a photo with their smartphone of pretty much anything each day (or whatever time interval wanted) to visually track its progression.  It aids in the process by showing a transparent version of the last photo to match up with the next one.  Then it turns the captured photos into a video or slideshow.

$1.99 | See Watch It Grow in the Marketplace

Weather Alert

Do you really want to know if tomorrow will be two degrees warmer than today or are you more concerned with whether it’ll be pouring?  Weather Alert bets on that latter.  The app is designed to automatically check the forecast and only alert users if there’s something they want to know.  Users can set the parameters by temperatures, rain, and severe weather, among others.
